TAKING SUPPLEMENT AFTER TRAINING
A lot of people have questions about the importance of taking supplements after training.
The main reason why you need to take a supplement after training is because while you are exercising you are putting a lot of stress on your muscles and many people think that they are gaining mass at the moment because their arms get swollen. However, that's not true!
You are "destroying" your muscles as you are exercising. This is why you need to take protein and carbs together after training. The protein will replanish your muscles while the carbs will recover your energy and bring glycogen to the muscles.
If you don't take these supplements after training, you'll probably lose mass instead of gaining it / some.
